Audio and telephone, operation
These instructions are intended to help
you become familiar with your
Mercedes-Benz audio system. They con-
tain useful tips and a detailed description
of the user functions.Operating safetyLocation of the audio system
The audio system control panel is located
behind a cover in the upper part of the cen-
ter console.
1Cover
Briefly press on the lower part of
cover1.
The cover opens automatically.
Warning!G
In order to avoid distraction which could
lead to an accident, the driver should enter
system settings with the vehicle at a stand-
still and operate the system only when road
and traffic conditions permit. Always pay full
attention to traffic conditions first before
operating system controls while driving.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your car is cover-
ing a distance of 44 feet (approximately
14 m) every second.
Warning!G
Any alterations made to electronic compo-
nents can cause malfunctions.
The radio, amplifier, CD changer and
telephone are interconnected. When one of
the components is not operational or has
not been removed/replaced properly, the
function of other components may be im-
paired.
This condition might seriously impair the
operating safety of your vehicle.
We recommend that you have any service
work on electronic components carried out
by an authorized Mercedes-Benz Center.

CD changer operation
General notes
Should excessively high temperatures oc-
cur while in CD mode,
CD TEMP HIGH will
appear in the display and the CD will be
muted. The unit will then switch back to
the last operating mode used until the tem-
perature has decreased to a safe operating
level.
Should excessively low temperatures
occur while in CD mode,
CD TEMP LOW will
appear in the display, but the CD will
continue to play.
Handle CDs carefully to prevent interfer-
ence during playback. Avoid fingerprints
and dust on CDs. Do not write on CDs or
apply any labels or other material to them.Only use original CDs. Using copied CDs
may create problems during playback.
Clean CDs from time to time with a com-
mercially available cleaning cloth. Do not
use solvents, anti-static sprays, etc. for
cleaning. Replace the CD in its case after
use. Protect CDs from heat and direct
sunlight.
Only use CDs, which bear the label shown
and that conform to the compact disc
digital audio standard (IEC 60908). You
can therefore only use CDs with a
maximum thickness of 1.3 mm.
iUse of CDs which do not meet this standard
may cause damage to the CD changer. Do not
play single-CDs (80 mm) with an adapter.
Your CD drive has been designed to play CDs
which correspond to the IEC 60908 standard.
If you insert thicker data carriers, e.g. ones that
have data on both sides (one side with DVD data,
the other side with audio data), they cannot be
ejected and will damage the drive.
Warning!G
The CD changer is a Class 1 laser product.
There is a danger of invisible laser radiation
if the cover is opened or damaged.
Do not remove the cover. The CD changer
does not contain any parts which can be ser-
viced by the user. For safety reasons, have
any service work which may be necessary
performed only by qualified personnel.
